| Acceleration | This is a change in velocity per time. |
| Distance | This is the measured value (always positive) from one point to another. |
| Energy | The capacity for doing work. It may be transformed from one form to another. |
| Force | In the second law of motion it is Mass X Acceleration. The ability to apply a change in velocity on a given object. |
| Gravity | This is an attractive force between any two objects due to mass. |
| Inertia | This is a measure of resistance to motion, by an object. |
| Joule | This is the SI (metric) unit of energy or work. |
| Kilogram | This is the standard SI (metric) unit of mass. |
| Mass | This is a measure of the quantity of matter. |
| Mechanical Advantage | The ratio of resistance force to effort force. |
| Meter | This is the standard SI (metric) unit of length. |
| Motion | This is a change in the position of a body with respect to time relative to a reference point. |
| Newton | This is the SI (metric) unit of force. |
| Newton's First Law | A law of motion that states that an object at rest stays at rest and one in motion stays in motion. |
| Second | This is the SI unit of time. |
| Time | This is a number, as of years, days, minutes, or seconds representing such an interval. The SI standard unit of this is the second. |
| Velocity | This is a change in distance per time. |
| Weight | This is the vertical force exerted by a mass as a result of gravity, expressed in pounds or Newtons. |
| work | The process of changing the energy of a system by means of forces. Force x Distance |
